Traction control hell

oguncemir · Sat Apr 10, 2021 7:33 am

Hi team;
First of all i have done a lot of modification on forscan by this forum support thank you to all.
However nowadays i realize that i louse up something in traction control ;
My issues are mentioned in below
1-Buttons and esc light are working correctly.
2-Traction control is being worked in all (esc on, esc off, esc full off) modes included 2wd 4H and 4L
3-If i press the button longly in third time, esc light is off and never works again. If i lock the doors and wait approx. one hour,i could activate lamp and buttons, but finally esc is still working then nothing changed on it as mentioned in above.

Did you backup the modules before they were modified?

I imagine the ABS module controls BS/VSC/TC/AEB/etc.
The factory configuration should be downloadable from https://www.motorcraftservice.com/AsBuilt after registering. (However, I have found some data is incomplete compared to what I read from the modules originally)

3. If the traction control button is held down "too long" it crashes the ABS module. Quick fix is remove battery terminal for a minute or leave it like you do.

No, I have no idea. Push button once, let go, hold until it flashes, let go and mine is disabled.

Possibly firmware changes in later vehicle to not allow it to be fully disengaged? Could be where your vehicle was manufactured with certain laws? Who knows. It is not a fault with the vehicle but will be firmware dependant on the ABS and PCM modules.
